This is a fairly old forum game that I found. I'm not sure wheter this has already been on here.
The person posting above you will post something they wish for, then you post that it's granted but somehow make it undesirable.
I wish I had a million dollars.
Granted, but it's all in pennies.
After you've corrupted the previous person's wish, post your own.
I wish I had a Liverpool season ticket.
